dimavery ma-50 (5 watt portable amp)

Hello,I consider buying a portable amp, I'm stuck between two choices, either Marshall MS2-C, or Dimavery MA-50. The problem is, I can't find any reviews of the dimavery amp, not to talk about a video with the sound being tested. I like the sound of the Marshall micro amp, but I'd like to hear something about the MA-50 first. They are being sold for the same price, and MA-50 packs a decent 5W speaker, the Marshall only 1W.Could anyone possibly provide any info about this amp? Thanks in advance
